T at? whom it may concern: I

Be it known that I, EDWARD R. liner, of

' Baltimore, Maryland, have invented a new and useful Improvement in Caliperin Devices for Si ature Gatherin Mac ines, which invention is fully set forth in the following specification.

This invention relates to-acali ering device for signature-gathering machines, and has for its object toprovide a device of this character which shall automatically stop the machine when the same in its operation withdraws from the hoppers of the machine more or less than the number of signatures (generally one) that it is desired it shall withdraw at each operation thereof, and incidental to the main portion of the invention, it has for its further object to provide means which shall. indicate to theoperator at what particular hopper or hoppers the inaccurate action of the machine has occurred. y

In machines of this character, it is desirable, as a generalthing, in the normal oper; ation of the achine, that one signature at a time shall ii; withdrawn from the hopper and piled on-a suitable table or tables for binding, and it sometimes occurs that the machine withdraws more than a single signature, where one is desired, or that it fails to withdraw a signature when one should be withdrawn, and the present invention is designed to provide means for detecting this inaccuracy in the operation of the gathering machine, and to at once stop the machine as a whole, and indicate to the operator at which hopper or hoppers such inaccuracy has occurred.

The inventive idea involved is capable of receiving a variety of mechanical expressions or embodiments, one of which, for the purpose of illustrating the invention, is shown in the accompanying drawings, but it is to be expressly understood that such drawings are designed for the purpose of illustratin the invention, and are not to be considers as defining the limits thereof, reference being hadto the appended claims for this urpose.

In sai drawings, Fi ure 1 is a transverse vertical section tirough a part of a signature-guthcring machine, such, for exam le,

as that shown and described inmy. pen mg application Serial No. 508,160, filed July 1 th, 1909, showing the essential features of the present invention'in side elevation;

is broken detail of a part of the machine with my inventionattached there to Fig. 31s a (perspective view of the invention as: ap lie tomy signature gathering machine; ig. 4 is a top plan v ew illustratingmy invention, parts bein shown in section; and Figs. 5, 6 and 7 are etails illustratin the construction and operation of the ca ipering device. 1

In said drawings, like reference numerals indicate like parts, 1 (Fig. 1) being a signature-hopper hav ng si natures 2 arranged therein, 3, a suction evice for drawing down the si atures one at a time in posi tion to be selzed by the revolvin signature carrier 4,- 4", and 5 is an OSCllfhtlIl" arm, which supports the folded edges of t e sigr natures between the withdrawing operations. The parts thus far described are, or .may be, substantially as shown in my application above referred to.

, Pivotally mounted at 6 on a depending 1 arm 7 attached to the frame of the machine, ,is a bell-cranl'r-lever 8, the short arm 9,013

which carries a roller 10, in a position toengage the surface of the signature 2 that has been withdrawn, and is in the act of being carried over by the carrier 4, 4. 'The upwardly projecting arm 11 of said bell crank lever is connected by a link 12 to a rocking bell-crank-lever, pivotedv at 13 to the frame-work of the machine, the short arm 14.- of said bell-crank-lever being connected to the link 12, which preferably is screw-threaded at each end, and engages nuts 15, 15', and which link 12 is also provided with a knurled Wheel or surface 16, by means of which it may be turned for the adjustmentof the parts.

17 is a horizontal arm of the bell-cranklever, which is pivoted at 13, said arm carrying on its outer end a laterally projecting squared lug 18 (see Fig. 7). Mounted to reciprocate on the frame-work of the machine is a movable member such as a T-shaped slide 19, which is held inplace to reciprocate in suitable ways by means of a plate 20, and which has formed in its upper' surface, and on the opposite end from the T, a transverse" groove 21, Fig. 7. A lever 22', pivoted at 23 to the frame-work of the machine, projects upward, and on its upper end has a 'pawl'24, having a rounded nose engaging in the groove 21 on the sliding T bar 19. Mounted on a revolving-shaft 25, suitably connected to the operativeparts lever.

' the arm 17 0 by the signature-carrier 4, 4, the lever armof the machine, is a cam 26, which engages the lever 22, preferably through the medium of a friction roll 27, ,lVOtGd to turn on a lug or bolt projecting rol'n the side of said 28 is a spring tending to throw the lever v22 from right to left, as shown in the drawings, and holdin the lever in operative engagement with t e cam 26.

29 is a spring yieldingly holding the pawl 24 in engagement with the groove 21, and 30 is a sprln normally tending to depress the bell-crank-lever 1417.

On the side of the sliding T-bar 19, there is formed a rectangular groove 31, whose dimensions are such as to just receive freely and easily the squared lug 18 on the end of the lever'bar 17, and the relative. position of the parts when adjusted is such that the sliding T bar 19, with its groove 31, registers with the squared lug 18 when a signa-' ture is in position on the signature-carrier 4, 4, as shown in Fig. 1. If, however, no signature is in position, the spring 30 slightly lowers the lever arm 17 so that the squared shoulder 32 of the groove on the sliding T-bar is engaged by a, stop such as the squared lug 18, and .the sliding T-bar 19' thereby held against movement. This position of the parts is shown in Fig. 5. If, on the other hand, more than one signature is withdrawn and passed under the roller 10 17 is raised slightly above the operative position, so that the upper squared shoulder of the lug 18 engages t e squared shoulder 33 of the groove 31, andin this position the sliding T-bar is restrained from movement. '{his position of the .parts is illustrated in %Vhen the sliding T-bar 19 is restrained from movement, by'reason of the failure to withdraw a signature, or by reason of more than one signature being withdrawn, as indicatd in Figs. 5 and 6, respectively, the action of the cam 26 in forcing the lever 22 to the right, causes the rounded nose on the pawl 24 to release its hold on the groove 21, the spring 29 yielding for this purpose, and the nose of the pawl then travels rearward on the upper face 34 of the T-bar, as shown in Fig. 6. Projecting upward from the pawl 24 is a broad lug 35, and immediately oversaid lug is a rock shaft 36 (see Figs. 2 and 3), having a downwardly extending lug 37 rigidly secured thereto, which, when the nose of the pawl 24 is in the groove 21, is just above the lug 35, but when the pawl 24 is raised out of the groove 21, the lug 35 engages the depending arm or lug 37 and acts to rock said rock shaft 36. The rocking of this shaft is utilized to throw the machine out of operation by disconnecting it from the motor. The particular means for effecting this disconnection from the motor will depend upon the character of motor em- Eloyed. For example, as shown in the rawings', the machine is o erated by an electrical motor, and the rocking of the shaft 36 acts to shift a switch 38, whereb the current is cut off from the motor. bviously, any other suitable means for disconnecting the motor might be employed, the specific means utilized for this purpose not forming an essential part of the invention, and being dependent, as stated above, upon' the character of motor in use.

A sleeve 39 (Fig. 3) is loosely mounted on the rock shaft 36, and has a depending arm or In 40, which is also in the .line of travel of t e broadened lug 35 on the pawl 24 when the latter is raised out of the groove 21 on the T-slide, but which is just above the lug 35 when the awl 24 hasits nose in said oove 21, so tl iat when the shaft 36 is rocked to stop the machine, the sleeve 39 is also rocked on the shaft 36. Said sleeve is provided with two lugs 41 and 42, a pin 43 on a part of the frame-work of the machine projecting between them for limiting the rocking action of said sleeve 39. The sleeve 39 has an indicating target 44 secured thereto, and the rocking of the sleeve correspond: ingly rocks the target. r

Thereis a calipering device of the construction shown arranged in connection with each signature-carrier, that is, one for each hopper on the gathering inachine, and the indicating targets 44 are preferably numbered from 1 upward, so that when the stoppage of the machine occurs, as the result of a defective operation, beside any given hopper or carrier, the displacement of such target will indicate to the operator at which hopper the defective operation has occurred.

-It will be at once apparent to those skilled j the relative arrangement of the parts and in the mechanical form of the various elements entering intothe structure, without departing from the spirit of my invention, and such variations are meant to be included in ,the claims.
